BETT focus: The importance of audio in classrooms
Despite taking up half of the term “audio-visual”, the impact of audio on offer at BETT seemed to be lacking. Although many of the latest interactive screens had integrated speakers, there was only a small cross-section of companies offering speakers or microphones to enhance both the classroom and a presentation theatre within an education establishment.
Studies have been carried out to prove the impact that classroom noise can have on students and Lightspeed’s latest Exciter technology takes this research into account. According to a study from 1994, a professor of Audiology proved that ELL (English Language Learning) children were affected by ambient noise in a classroom. Word recognition by these pupils was affected by volume, distance from the speaker and how the audio was distributed, but all of the children; both native and non-native had better understanding when little or no additional noise was created, through issues like feedback, or buzzing electronics. In a current situation where classrooms are full to the brim, distance cannot often be altered, so teachers need to be as audible as possible, regardless of the room size.
Lightspeed have taken these ideas to create a speaker that enhances both audibility (the volume) and intelligibility (the clarity) in the classroom by using a panel style instead of a cone-shaped speaker. This helps distribute soft consonant sounds and creates a clear sound without having to use maximum volume. This simple yet effective technology creates a natural voice for the teacher and feedback is eliminated regardless of where the teacher is located in the room.
